Step 9

Now we have a rust and metal texture. The next step is to mask out portions of the rust. Begin by adding a layer mask (Layer> Add Layer Mask> Reveal All) to the "Rust" layer.

Step 10

Open the Image menu and select Apply Image. The Apply Image tool will let us tell Photoshop to copy the background layer into a layer mask In the Apply Image window, select Background as the layer and checkmark the Invert setting. Click OK when done.

Step 11

Now you should see the photo you started out with as a rusted metal image. The results are too perfect to look like something hand made so we'll need to distort the layer mask to make it look more natural. First, we'll increase the contrast using the Brightness/Contrast tool (Image> Adjustments> Brightness/Contrast). In the Brightness/Contrast tool, adjust the settings to achieve a look that you like. It may be helpful to use the legacy Brightness/Contrast tool instead by checking the "Use Legacy" option.

Step 12

Now we'll distort the layer mask slightly so that the lines are a little more wobbly. For this, we'll use the Glass filter that can be found in the Filter> Distort menu. Open the Glass filter tool and adjust the settings to create a slight distortion.

When you are done, you should have an artistic rusted metal image. It may look flat, but we'll add some depth to it in the next steps.

Step 13

To add depth to the flat image, we'll be using Photoshop's lighting filter. First, select to activate the rust layer (not it's layer mask). Open the Filter> Render layer and select Lighting. Play around with the Lighting tool to create the lighting effect that you would like but there are a few settings that needs to be set according to these instructions. First, set the gloss and material to -100. Depending on which lighting effect, these property settings may or maynot produce a significant result. But there is one setting that will create a strong effect. This is the Texture Channel setting. Select Red as the texture channel and adjust the height. The lighting tool isn't able to show a full preview, so you will have to experiment with this a few times. Start off with a height at 25 and click OK. If it doesn't give you the results you like, press Ctrl+Z to undo and open the Lighting filter again (Filter> Render> Lighting). The lighting tool should remember your setting so you can simply adjust the height of the texture channel.
